| タイトル | Node.js @svgdotjs/svg.js 3.2.5 Prototype Pollution |
|---|
| 説明 | @svgdotjs/svg.js version 3.2.5 is affected by a prototype pollution vulnerability in the public EventTarget.on() event registration API. The event string is split into an event name and namespace and then stored in an internal object bag without rejecting prototype-related keys. When an attacker-controlled event name or namespace contains __proto__, the write can traverse ordinary JavaScript prototype access and create properties on Object.prototype.
An attacker who can influence event names passed to EventTarget.on() may be able to inject inherited properties into newly created objects. Depending on how the application later uses plain objects, this may lead to logic corruption, denial of service, unsafe inherited-property checks, or application-specific security impact. |
